Hello, I am having a problem with AIN2 pin.

The other pins are well working like if I connect AIN0 to GND, it shows few miliV only which is very close to GND. However, for AIN2 pin, it shows about 500 mV. Why does it happen? Even, I am not using with IDAC function.

And according to your tutorial, I checked that your AIN2 (microVolt) is about 800 mV.

Thank you for reading.

Thank you very much for this library.

ESP32 has got two SPI interfaces namely VSPI (default) and HSPI. When passing a custom SPIClass to use the HSPI interface the setup gets stuck after reading a single value. After several attempts to assign different pins and avoiding restricted pins, I found that there is a method ( void ADS1220_WE::command(uint8_t cmd) ) in the file ADS1220_WE.cpp where there the global SPI is used instead of custom member_spi assigned in the constructor .

Changing the line SPI.transfer(cmd) to _spi->transfer(cmd) solves the problem when assigning a different SPI interface in ESP32.

Kindly advice if this change is correct and if it could be a possible bug fix

I set the sensor to continuous mode, and then collected data. I found that the speed of the sensor is very slow, and it can only collect 30 times per second，How to improve the acquisition speed? For example, collect data 100 times per second?

How to use "SPIClass *s" in ADS1220_WE(int cs, int drdy, SPIClass *s), I would be grateful if you could tell me
